利用木薯光系统II（PSII）最大光化学效率（Fv／Fm）量化木薯受到干旱胁迫的程度．并测量木薯叶片与离层的内源乙烯在不同程度干旱胁迫下的量．以探讨内源乙烯的产生、Fv/Fm胁的下降速度与木薯抗旱性之间的关系。结果表明，抗旱性越强的品种，Fv/Fm下降速度越慢，内源乙烯上升的时间也越靠后。

To quantify the level of cassava drought stress, cassava Photosystem II （PSII） maximal photochemical efficiency （Fv/Fm） has been used in this study. At the same time, we measured the content changes of endogenous ethylene in cassava leaves and abscission zones under varying drought stress. We aim to determine by analyzing the present experiment results, the relationships between drought resistance of cassava, the production of endogenous ethylene, and the rate of decline in Fv/Fm value. Our results showed that cassava varieties with later ethylene emission and slowly decreasing Fv/Fm are more tolerant to drought.
